How many cubes of 10 cm edge can be put in a cubical box of 1 m edge?
Advertisements
उत्तर
We have,
Edge of the cube, a = 10 cm and
Now,
The number of cubes that can be put in the box `= ("Volume of the cubical box")/"Volume of the cube"`
`="l"^3/"a"^3`
`=100^3/10^3`
= 103
= 1000
so the number of cubes that can be put in the cubical box is 1000.
